FAQ

What are the physical and chemical properties of tetraethylammonium sulfate (CAS: 16873-13-5)?

Tetraethylammonium sulfate (CAS: 16873-13-5) is a colorless or white crystalline solid. It has a molecular weight of approximately 214.3 g/mol. The compound is highly soluble in water and ethanol but insoluble in non-polar solvents. It is mildly basic and readily reacts with acids. It is stable under normal conditions but should be stored in a cool, dry place away from direct sunlight.

How is tetraethylammonium sulfate (CAS: 16873-13-5) typically synthesized?

Tetraethylammonium sulfate is typically synthesized by reacting tetraethylammonium hydroxide with sulfuric acid. The reaction is carried out in an aqueous medium at room temperature. The product is usually isolated by filtration and washed with water to remove any unreacted starting materials. The yield is generally high, and the product is pure upon recrystallization from water.

What industries use tetraethylammonium sulfate (CAS: 16873-13-5)?

Tetraethylammonium sulfate (CAS: 16873-13-5) is used in various industries, including pharmaceuticals, where it is used as a medium for ion exchange chromatography and as a stabilizer for enzymes. It is also used in polymer science for the synthesis of certain types of polymers. Additionally, it is employed in the semiconductor industry for etching processes and as a component in sensors.

What precautions should be taken when handling tetraethylammonium sulfate (CAS: 16873-13-5)?

When handling tetraethylammonium sulfate (CAS: 16873-13-5), it is important to use appropriate personal protective equipment, including gloves and safety goggles. The compound should be handled in a well-ventilated area or under a fume hood to avoid inhalation of aerosols. In case of a spill, it should be cleaned up immediately using appropriate absorbent materials. Chemicals should be stored in a cool, dry place, away from direct sunlight and heat sources. Always refer to the safety data sheet (SDS) for detailed handling and storage instructions.
